If the NV SEL DIP switch is:
ON (enabled) – The Edge Router module uses configuration settings
stored in its NVRAM. If NVRAM does not contain configuration settings, the
Edge Router modules are assigned to the Isolate_1 network.
OFF (disabled) – The Edge Router module uses DIP switch settings.

Selecting a Network

In an unmanaged ONcore hub, the DIP switches determine the network
